BKT-140 drug substance is a highly selective chemokine receptor (CXCR4) antagonist, which is developed by Biokine as a novel therapy for Multiple Myeloma (MM, a type of blood cancer). The unique combination of activities of BKT140, i.e., the induction of the exit of blood cells such as stem cells and mature cells from the bone marrow to the peripheral blood, coupled with specific induction of MM cell death by BKT-140, represents a novel therapeutic strategy against MM.
